GPU Compute / Accelerators / Re: Intel Arc Support in Kernel 6.8

« Last post by Hasturtium on February 09, 2024, 05:50:57 pm »

I'm cautiously optimistic, I've been literally looking for an excuse to pick up an arc gpu as it'd be perfect for my blackbird. One question, why is the Huc microcontroller not likely to be supported and what limitations would there be on video encoders without it?

To my recollection that microcontroller won’t be supported from Battlemage/future IGPs, and the driver maintainers consider implementing support outside the x86-only i915 driver to be too pernicious to be worth bothering with. IIRC the microcontroller’s responsible for configuration of parameters to be passed to the video encoder, so outside of some default setting it won’t be configurable. Once kernel support for the Xe driver is verified working I’ll throw my little Arc A380 in and take it for a test drive.

Talos II / Re: OpenBMC password

« Last post by bobpaul on February 07, 2024, 10:09:18 pm »

I'm still curious on how logging into the serial console is suppose to allow you to reset the password though. I don't see any OpenBMC documentation about it. I found this: https://docs.graphcore.ai/projects/bmc-user-guide/en/latest/serial-rescue.html ...but is it specific to graphcore processors or generic to OpenBMC?

I tried the instructions at graphcore.ai with no luck. But the instructions on the wiki for Resetting the BMC's Persistant Storage worked for me on two systems. After wiping the persistent storage, I was able to log into the BMC with the default password and get all the firmwares updated.

Has anyone tried this yet?

As an MPC I also use the Radeon with the switch after loading the operating system, he himself makes the switch from AST to Radeon.

On Petitboot I always use the framebuffer and on the OS I switch to the RDNA1 GPU.

General OpenPOWER Discussion / Using Older Radeon Cards On Talos II.

« Last post by xilinder on January 28, 2024, 11:58:53 am »

While messing around with F39 install and my 3 input monitor and the aspeed select jumper.

Sometime ago my fancy graphics card went belly-up and I installed a old RV-730 card. Of course it required the firmware blobs installed into petitboot for it to work, being lazy, or just not finding the time to go thru the pain of doing so, I have been running the T2 on the Aspeed VGA.

Upon running F39 install I noticed the DVI input was active on my monitor when the Aspeed jumper was on. The RV-730 was active! Wow...!

I reboot and just let it go thru all the startup again, without the F39 USBstick installed. This time it booted Debian 12 on the RV-730. This is using the 6.1.0-17 kernel. Another try using 6.1.0-16 kernel failed to boot the RV-730.

Hmm. lets try another old Radeon card. So installed a HD-6850 (BARTS)
card and it also works.

Now you can not see which OS to boot without installing the firmware into petitboot,but the keyboard is active and if you count how many times you click the up arrow key you can select other than the default OS to boot. Cool.

I only run Debian, so switch-on and it boots on the old Radeons without firmware in petitboot. With the jumper on it displays the boot sequence to a certain point then the display changes to the card and I have to select the DVI input on the monitor. If I do not have the Aspeed VGA plugged in then I miss all the boot stuff on the display and the first thing I see is the GUI login screen.

Questions?

Petitboot doesn’t work with the GPU now, no. I can always use the network console if the screens don’t come up after a minute, or reconnect the VGA to watch the IPL logs.

Does that actually work in Petitboot?

I finally got the wx9100 working on newer kernels by flashing an empty firmware directory to BOOTKERNFW .
